I got as far as downloading OSG and looking at the API for it. I'm 
interested in working on it, but I don't have free time to commit like I 
used to. I'll try to stay involved, anyways.

My first question is, where do we start?

A python binding for OSG would be a good place to start then?

(As an aside, I'm not proficient in python. I realize that I could learn 
it on the fly, but I do like using C++ whenever available. Would it be a 
problem to have a mix of C++ and python, especially if they can use a 
wonderful interface such as Boost.Python?)

Um, I'm mostly interested in drawing and picking. Not that I don't think 
the API doesn't need work as well, but it's not my first pick of things 
I'd like to work on.
